Solution

If it's for purpose of breadcrumbs only you can do the following:

Modify your navigation array as below - remove specific product page spec. and add ID to products page.

<?php
return array(
    // All navigation-related configuration is collected in the 'navigation' key
    'navigation' => array(
        // The DefaultNavigationFactory we configured in (1) uses 'default' as the sitemap key
        'default' => array(
            // And finally, here is where we define our page hierarchy
            'home' => array(
                'label' => 'Home',
                'route' => 'home',
                'pages' => array(
                    'sitemap' => array(...),
                    'productHome' => array(
                        'id' => 'productHome',//<<< Page unique ID
                        'label' => 'Product',
                        'route' => 'product',
                        'controller' => 'Product',
                        'action' => 'index',
                    ),
                  ),
                ),
            ),
        ),
    ),
);

In Application\Controller\Product::product() add at the end the following code. This adds 'dynamically' new sub page to product index page in navigation static structure. Also notice that I presume you have got actual product instance available in $product variable.

    $navigation = $this->getServiceLocator()->get('Navigation');
    $page = $navigation->findBy('id', 'productHome');
    $page->addPage(array(
        'uri' => $this->getRequest()->getRequestUri(),//current page URI
        'label' => $product->getName(),//<<<<< product name
        'active' => true,
    ));

Problem

I'm a newcomer to Zend Framework 2 and I´m trying to generate dynamic Breadcrumbs using ZF2 but without success. I used http://adam.lundrigan.ca/2012/07/quick-and-dirty-zf2-zend-navigation/ as a base for my work and as described I constructed the sitemap for the routes exposed by my modules. Example: ``` // config/autoload/nav_zfcuser.global.php <?php return array( // All navigation-related configuration is collected in the 'navigation' key 'navigation' => array( // The DefaultNavigationFactory we configured in (1) uses 'default' as the sitemap key 'default' => array( // And finally, here is where we define our page hierarchy 'home' => array( 'label' => 'Home', 'route' => 'home', 'pages' => array( 'sitemap' => array( 'label' => 'Sitemap', 'title' => 'Sitemap', 'route' => 'sitemap', ), 'aboutus' => array(...), 'privacy' => array(...), ), ), ), ), ); ``` Then to render the breadcrumbs used the following view helper: ``` <?php echo $this->navigation()->breadcrumbs('Navigation'); ?> ``` This works fine and for example if I navigate on mywebsite.com/sitemap the rendered bredcrumbs will be. Home > Sitemap The problem is when I start having dynamic URL´s (e.g. with product ID´s). On the module.config.php the routing is.. ``` <?php return array( 'router' => array( 'routes' => array( (...) 'productHome' => array( 'type' => "Literal", 'options' => array( 'route' => "/product", 'defaults' => array( '__NAMESPACE__' => "Application\Controller", 'controller' => "Product", 'action' => "index", ), ), 'may_terminate' => true, 'child_routes' => array( 'product' => array( 'type' => "Segment", 'options' => array( 'route' => "/:idProduct[/:name]", 'defaults' => array( '__NAMESPACE__' => "Application\Controller", 'controller' => "Product", 'action' => "product", ), ), 'may_terminate' => true, ), ), ``` The routing defined above (module.config.php) translates into the following URL structure: mysite.com/Product/:idProduct[/:name] So constructing the sitemap to reflect this structure should be: ``` // config/autoload/nav_zfcuser.global.php <?php return array( // All navigation-related configuration is collected in the 'navigation' key 'navigation' => array( // The DefaultNavigationFactory we configured in (1) uses 'default' as the sitemap key 'default' => array( // And finally, here is where we define our page hierarchy 'home' => array( 'label' => 'Home', 'route' => 'home', 'pages' => array( 'sitemap' => array(...), 'productHome' => array( 'label' => 'Product', 'route' => 'product', 'controller' => 'Product', 'action' => 'index', 'pages' => array( 'product' => array( 'label' => 'Product', 'controller' => 'Product', 'action' => 'product', 'route' => 'product/:idProduct[/:name]', ), ), ), ), ), ), ), ); ``` Refreshing the products page on the browser mywebsite.com/product/flv6n768/ProductName no Breadcrumbs are displayed. How can I pass 'idProduct' and 'name' params so that when I call the view helper ``` <?php echo $this->navigation()->breadcrumbs('Navigation'); ?> ``` It renders: Home > Product > idProduct (not visible) > name of the product ?
